class_docstr: ParameterSystem is a subclass of GroupParameter that manages a tree of 
  sub-parameters with a set of interdependencies--changing any one parameter
  may affect other parameters in the system.
  
  See parametertree/SystemSolver for more information.
  
  NOTE: This API is experimental and may change substantially across minor 
  version numbers.
